The following pictures shows part of the result from "technology map viewer (post-mapping)" for a simple FSM design. As I double click on the right LOGIC_CELL_COMB, nothing is shown. I expected to see in the internal structure (gates). Should I do something else?

Normally, the farthest you can go with technology map viewer (post-mapping) is the macrocell. If you want to see the logic gates, you will have to use the RTL viewer.
It is Quartus.
The RTL diagram is shown below. The FSM is shown as the current_state block. When I double click on the block, I see the FSM and not the flip flops.
So, the map viewer shows the flip flops while not showing combinational logic. On the other hand, the RTL is the reverse.

Yes, the technology map viewer shows the flip-flops. It also shows the combinational logic cell, but as a unit cell. It doesn't get to gate level. If you look at the netlist navigator, as you expand down, you will see ports, registers and atoms. These are basically ports, flip-flop registers and combinational logic cells, respectively. They are the farthest you can go with Quartus Prime.
With RTL viewer on Quartus Prime, you can only expand down to multiplexers, operators and registers (flip flops), and even logic gates where you explicitly used OR, AND,...operators.
I do not know about this. I am not with my PC at this time. Please can one post a confirmation screenshot for the purpose of learning? I'll check later but a screenshot will be well appreciated.
